Answer:Option 'C' is correct.
Step-by-step explanation:
Since we have given that
Now, we draw the graph :
According to question, solution point is (-3.2,2.5)
At this point, both the equations intersected at .
By Option 'C' we can see that
and that is our required answer from the graph.
Hence, Option 'C' is correct.
Answer:
Quadrant II
Step-by-step explanation:
(0,-5) on graph would lies on II quadrant
hope it helps!
Remark
The equation is job1/ time + job2/time = job3/time
Discussion
job one is the time it takes one of the workers to complete the job.
job two is the time it takes the other workers to complete the job
job three is the time it takes to do the job together.
Givens.
Let Marcus's time = m
Let Tony's time be =t
Let their together time = t1
Equation Substitution and solution.
1/m + 1/t = 1/t1
1/6 + 1/4 = 1/t1 The common denominator on the left is 12.
2/12 + 3/12 = 1 / t1
5/12 = 1/t1 Cross multiply.
5*t1 = 12 Divide by 5
t1 = 12/5
t1 = 2 2/5
t1 = 2.4 hours
Cost
1 hour = 43 dollars for labor.
2.4 hours = x dollars for labor.
1*x = 43 * 2.4
x = 103.2 dollars. <<<<< Answer
Answer:
8 cm
Step-by-step explanation:
Megan's scale of drawing : car is 3cm : 2m
or
3 cm drawing ---> 2m actual length
1 cm drawing ---> (2/3) m actual length
Given Megan's drawing is 6 cm, hence,
6 cm drawing ----> (2/3) x 6 m = 4 m
Hence the actual car is 4 m long
Ivan's scale of drawing:car is 2cm : 1m
or
1 m actual length ---> 2 cm drawing
we know from above that the actual car is 4m long, so
4m actual length ---> 2cm x 4 = 8 cm drawing length.
